Two of the largest problems in the world are food supply and fresh clean water. Three-forth of the world is filled with water. Most of these water are dirty, salty and therefore undrinkable. In fact, of all the water on earth, only very few percentage of water is available for us to use and drink. On the other hand, finding drinking water in this polluting world in a very easy way is a nightmare. But an Italian designer Gabriele Diamanti doesn’t believe that. He has made a solar oven called Eliodomestico that can transform salty water into drinkable water. 5 liters of salty water can be transformed into drinkable water daily.
